Green Energy



Rising electricity prices means higher operating costs for businesses. A solar power system can immediately reduce costs and in turn business risk. GEWA looks at each business individually, including assessing your load profile to accurately recommend an appropriate system. Through our internally developed investment calculator we will provide you with a detailed final report to assist your decision making.

The report includes:

  • Expected Solar Yields
  • Expected Returns
  • Net Present Value (NPV)
  • Investment Rate of Return (IRR)
  • Payback Periods
  • Scenario Analysis
  • Depreciation Tax Benefits



Why Green Energy?

With years of experience and hundreds of installations across Western Australia, GEWA offers you piece of mind when it comes to selecting the right brand and product for your business.


GEWA uses net present value to determine an investments worth. This takes into account your finance or opportunity costs for investing and reflects it in a time series of discounted cash flows. This is the standard method for using the time value of money to appraise long-term projects.
